PENCIL.

Specification of Letters Patent.

Application filed June 5, 1920. Serial No. 886,858.

To all whom it may concern:

Be it known that I, WALTER MEYNER, a citizen of the United States, and a resident of New York city, county and State of New York, have invented certain new and useful Improvements in Pencils, of which the following is a specification.

My invention relates to writing implements and aims to provide a self-luminous pencil, crayon or the like which will be relatively inexpensive and will be entirely practical.

In a preferred form, the pencil body is constructed with a bore for the writing material and this bore is left open at, or along the side of the pencil body so as to expose the writing material which is of a selfluminous nature.

The invention involves other novel features as will be fully disclosed in the course of the following specification which is to be considered in connection with the accompanying drawing, wherein: I

Figure 1 is a side elevation of an approved form of the pencil, and y Fig. 2 is a top plan view of the same.

The pencil body is designated 5 and may be of any desired shape or size. This supporting or carrying body is constructed with a bore 6 to receive the writing material 7 and this bore is, in the illustration, shown as open at 8 entirely along one side of the pencil, so as to expose the writing material the full length of the pencil.

For the writing material I prefer to employ graphite or any other suitable writing agent or pigment, with which is incorporated a self-luminous material of the type ordinagily employed in so-called radlum If desired, the core or writing agent may terial, which may contain a sufficient proportion of oily substance to keep the same sufiiciently soft for writing purposes. If no pigment or coloring matter is used, the marks made by the pencil may be undecipherable in the light, but will appear plainly in the dark by reason of their self-luminous character. e

The exposure of the writing material along the edge of the pencil provides an easy method of molding the core in place in the pencil body and also makes the material self-restoring by reason of its exposure to the light. The slot or groove 8 in the side of the pencil body, and which communicates with the central borev therein is preferably of less width than the bore, as indicated, so as to cause the filling of writing material to be keyed securely in place within the pencil body.

What I claim is:

1. A self-luminous writing implement comprising a supporting body having a bore open at one side thereof and a core of selfluminous writing medium in said bore and exposed at the opening in the side of the supporting body.

2. A writing implement comprising a pencil body having a longitudinal bore thereinopen at one side the full length of the pencil body and a self-luminous writing medium in said bore and exposed the full length of the pencil body.

3. A writing implement comprising a pencil body having a bore and a slot in the side of the pencil body of less width than the bore and communicating therewith and a filling of self-luminous writing material in said bore and slot.

In witness whereof, I have hereunto set my hand this 3rd day of June, 1920.

WALTER MEYNER.
